ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 672,660, dated April 23, 1901.

Application filed July 31, 1900.

2'0 ctZZ whom it may concern:

Be it known that we, WALTER S.Woo1), residing in the city of Kalamazoo, and SAMUEL DOU GLASS, residing in the village of Schoolcraft, in the county of Kalamazoo and State of Michigan, citizens of the United States, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a specification.

This invention relates to improvements in roller bearings, and more particularly to roller-bearings for vehicles.

The objects of the invention are, first, to provide a roller-bearing for vehicles which may be applied to wheels in common use and in much the same manner that ordinary axleboxes are now applied, so that the wheel and axle will have the same general appearance as now; second, to provide in a roller-bearing improved end bearings for the rollers, where by the rollers serve to hold the wheel or boxing on the axle or shaft and prevent longitudinal displacement of either and which will also allow the shaft or axle to work in an inclined or vertical position as freely and with as little friction as it would in a horizontal position; third, to provide improved means for retaining the rollers in position when the Wheel or boxing is removed from the axle or shaft; fourth, to provide improved end-bearing rings or collars for the rollers to bear against which may be readily detached from the boxing or axle for convenience in manufacture and repairing; fifth, to provide in a roller-bearing improved means of excluding dust and dirt therefrom. Further objects will more definitely appear in the detailed description to follow. We accomplish these objects of our invention by the devices and means described in this specification. 1

, The invention is clearly defined, and pointed out in the claims.

A structure embodying the features of our invention is clearly illustrated in the accompanying drawings, forming apart of this specification, in which-- Figure 1 is a longitudinal sectional elevation through a hub of an ordinary vehiclewheel, taken on a line corresponding to line 1 of Fig. 2. Fig. 2 is atransverse sectional elevation taken on line 2 2 of Fig. 1, showing alerial No. 25,378. (No model.)

the relation of the rolls to the spindle, boxing, and hub. Fig. 3 is an enlarged detail elevation of the roll-retaining ring E. Fig. 4. is a transverse detail sectional elevation taken on a line corresponding to line 4 4 of Fig. 3, with the end of one of the rollers in position. Figs. 5, 6, and 7 are detail longitudinal sectional elevations in which modifications of certain parts appear, which will be more fully referred to hereinafter.

In the drawings all of the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is an ordinary hub of a vehicle-Wheel.

B is the axle.

C is the boxing, tapered on the outside sub stantially as those now in common use. A series of rollers D are interposed between the axle B and the boxing C. These rollers are square at their ends and provided with small projecting pins D at the center of each end, as particularly shown in Figs. 1 and t.

Detachably secured to the boxing O at each end of the rollers are annular end-bearing rings E E. These rings serve a double purpose-that of forming end bearings for the rollers and of retaining the rollers in place in the boxing when it is desired to remove the wheel from the axle. A small groove a is formed on the inner face of each of these rings, (see Figs. 1, 3, and 4,) into which the small pins D on the ends of the rollers D project. These pins do not contact with the sides of the groove when said rollers are in their proper working position; but when the wheel is removed from the axle they will be supported by the grooves a, and thus the rollers will be retained in the wheel in proper position to be replaced on the axle,while the possibility of any becoming misplaced or lost is entirely obviated.

The inner faces of the annular end-bearing rings E E are slightly beveled at a, against which the ends of the rollers hear at their peripheries. This serves to retain the rollers in position and prevent longitudinal displacement of the same with a minimum of At the outer end of the boxing G friction.

'and to. exclude dust and dirt therefrom.

At the inner endzof theboxingC-is-aring: C, screw-threaded thereto and-turned firmly against the bearing-ring E at that end ofthe boxing for the purpose of retaining the same in position. collar B of axle B quite closely, it being,

preferably, only loose enough to revolve freely The ring R .-at the inner end of;

thereon. boxing O is provided with a rearwardly-extending flange E", against which ring 0" bears. ring-b, of feltor other suitable material, for the'purpose'of excluding dust: and dirt from the bearing.

Arranged on the axle atea'ch end-.of the rollers are collars 6-6, which alsohavetheir facesslightly beveled, the-same the annular-rings E E. These collars e e are forthe purpose of retaining'the rollers inposition on the shaft or axle and prevent longitudinal displacement of the same. It is obviousthat with the annularend-bearing rings E E, secured to the boxing, and the'collars e e,- secured to the axle or shaft, with the rollers interposed between said rings and collars, any longitudinal displacement of the boxing or the axle orshaft is prevented and all revolving parts are held in their properrelation without the use of any other or additional means. It is also obvious that with the faces of said rings and collars'slightly beveled the ends of therollers will bear-against the faces only at their peripheries,-where there'ispractically no movementto cause friction at the time of actual contact. Therefore thefriction on the ends of the rollers is reduced to a minimum, and they will run-as free in an inclined or vertical position as in ahorizontalposition. This feature is of greatimportance in roller-bearings for vehiclesand for use in other places Where there :is more orless' end thrust on the bearings,which causes a great amount of frictionand-which our device practially obviates.

A nut B is screw-threadedto the outer end o'fthe axle. The beveled collar e at that end is" preferably formed on said nut, although-it might be otherwise produced. The collar 6 at the inner end of the axle is preferably integral therewith, though :it could be otherwise produced.

In Fig. 5 we'show a modification in which the ring E corresponding to the annular ring E inv Fig. 4, is made'integralwithnut C and the groove a is omitted. 'JEhe'ringE at the innerend of boxing 0, corresponding to the ring E in Fig. 1, is made integral with said boxing, and the groove a isalso omitted. The little pins D are also omitted from the ends of the rollers D.

In Fig. 6 we show another. modification in which the ring E at the inner end of the box- Ring 0 embraces the ordinary This leaves an annular space for a tor-n ut1C-may--be.n1ade :int egral withboxing C;Ibut such. a structure wouldbedi'fficult and expensive to'mannfacture.

Fig. 7 illustrates still another modification,

.in which a groove a, corresponding to the groove a in the annular rings E E, (shown in Fig. 1,) is formed in collar e of the nut C, .which .is .made to project from the axle B sufficiently for this purpose. Of course the groove a at the inner end of the axle would 'be formed in the collar 6' at that end in the same man ner,andis-therefore not shown. It is obvious that this structure is perfectly pract'ical 'and 'in=many cases inight be preferred,

as it matters but little-whether the rollers are retained in the boxing or around the axle when the wheel is separated from'the axle, as the object in retaining them to either isto preclude the liabilityof-their -becominglost or misplaced.

It'will be observed that with the annular ri'ngs'EEsecuredto the boxing at each end of the rollers the boxing thus forms'an oil-receptacle capable of holding a=considerable quantity of oil, whereby all parts-of the'bearing-arekept constantlyand thoroughlylubricated. =-Oil*nraybe supplied-by removing the nuts O and B. Othermeanscould be'provided for ;admitting'the oil.

:It willbe observed that our improved rollerbearing in its 'most approved form is practicallydust-proof; which a =very important and .desirable feature in 'all roller-bearings, and especiallythoseapplied-to=vehicles.

We also-desire to state that while weihave shown our improved roller bearingsapplied to an :ordinary vehicle-wheel or axle i'tmay be adaptedto wheels with metal 'hubs, bicycles, car-axles, and journal-bearings ingeneral.

We also desire to state that while we have shown'our improved roller-bearing in-its most approved form we are :a-ware that it may be greatlyvaried without departing'from the-essential featu res of on rinvention.
